New York solar guide
Find a verified solar installer in Nassau County, NY
Nassau County homes are often close together, with established trees and plenty of roofs that were built decades ago. A free satellite roof check gives you a first look before you talk with verified, licensed installers.
What is different about Nassau County
Nassau is one of the more densely developed parts of Long Island. Close neighboring houses and tall street trees can shade a roof, so it helps to look at real sun exposure before you request quotes.
Many Nassau houses are older, and roofs may be nearing replacement. Ask about roof condition up front so you do not pay to remove and reinstall panels later.
Electric service generally runs through LIPA, with some villages having their own municipal service. Check your bill and ask installers about the interconnection timeline.

Frequently asked questions
Does Solar Entry install solar panels in Nassau County?
No. Solar Entry does not install. We offer a free satellite roof check and help Nassau County homeowners choose verified, licensed installers, including Infinity Solar, an installer partner that works in New York and Connecticut.
Will my neighbors' houses or trees shade my roof?
They might, especially on tight lots. The roof check shows shading from above, and installers assess it on site. Compare quotes based on realistic production rather than best-case numbers.
Which utility serves Nassau County?
Most homes are served through LIPA, though some villages have municipal electric service. Confirm with your bill and your provider.
Do villages within Nassau have their own permit rules?
Permits are handled locally, and incorporated villages can have their own building departments. Ask your installer who issues the permit at your address, and confirm with the village or town.
Is a flat or low-slope roof a problem?
Often not, but the mounting approach differs and roof condition matters. An installer will assess it on site.
What tax and program questions should I ask?
Ask about New York programs such as NY-Sun, property and sales tax treatment, and how your utility credits extra power. Terms change, so verify each.
